Natalie Green, a 27-year old ballet PR, is devastated when her best friend Barbara - a firefighter - gets married. Natalie - seemingly meek, never angry - fears being left behind. She is silver girl, because she always comes second. When Nat meets the apparently wild Chris at the wedding her good girl veneer cracks, and she starts an affair. To top it all, thanks to Chris's bad influence and her own hang-ups, she loses her job. But while Nat is busy blaming Babs for abandoning her, it becomes clear that she's not facing up to the real problems starting her in the face. Like her self-esteem and body image. Let alone the fact that Babs is developing marriage problems, Babs' brother Andy adores her, Frannie the feminist is untrustworthy, and that she has much unfinished business with her family. It'll get worse before it gets better....
